GATE-HINGE CONSTRUCTION.

Specification of Lett rs1 atent Patented 1\Ia,y 30, 1922,

Application. filed. July 29, 1920. Serial No. 399,722.

T 0 all whom it may concern.

Be it known that I, Bonner l\'IoLAUor-ILIN, a citizen of the United States, and a resident of the city of Monmouth, in the county of \Varren and State of Illinois, have invented certain new and useful Improvements in a Gate-l-Iinge Construction; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

My invention relates more particularly to a hinge construction which is strong, durable and so connected to the gate that the tendency to shear the connections is practically removed.

-It is therefore an object of my invention to construct a hinge connection which is braced against shearing stresses, and which has overlapping parts to produce a double thickness of metal at the points of greatest stress.

Further objects and advantages reside in the novel structural details and arrangement as will be more specifically hereinafter pointed out.

The invention (on a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a perspective view of a gate embodying my invention.

Figure 2 is an enlarged fragmentary View showing the hinge connection.

Figure 3 is a top view of a fragment of the gate showing the hinge construction.

Figure 4 is a section on line 44 of Figure 2, showing the interlock.

As shown on the drawings:

Referring now to the drawings, in which similar reference numerals indicate the same features in different figures thereof, 1 represents a gate suspended by means of my novel hinge mechanism upon a pair of anchoring bolts or hooks 2, the lower one being screw threaded in a post 3 and the upper one being secured in said post by nut 4. The hinge connections comprise a plurality of members some of which are designed to assume the vertical load component and the others for taking the horizontal load component and the bending moment. The latter is so constructed and connected that a rigid construction results therefrom.

In the present embodiment of my invention, I construct a hinge member or hearing block 5 having a bearing aperture 6 adapted to receive the hook-of the anchoring bolts '2. Each member 5 has a'depending leg which has a horizontal foot 7 for supporting the gate and taking the vertical load thereof. The depending leg of the lower member 5 has a rounded projection 8 adapted to :abut the rounded edge 9 of anchoring bolt 2 to preclude the gate from being raised when it is .closed. The hinge members 5 are preferably secured to the rear ends of the upper and lower boards of the gate 1, the feet 7 underlying the boards as shown in Figures 1 and 2, and preferably bolted to the struts 12. Further, the bearing hubs of these hinge members 5 are provided with upper and lower lugs 10 and 11, between which the horizontal hinge members of the gate are ada ted to fit.

T 1e gate 1 has a novel construction to provide a rigid section at the rear end thereof that prevents sagging and reduces the shearing stresses on the bolts or rivets that secure the hinge members. As shown in Figure 1, the gate has two pairs of vertical struts 12 bolted or riveted thereto and spaced apart as is common in gate constructions. To these struts 12, I secure my hinge members 13 and 14 by means of bolts 15, the hinge members 13 being on the near side and the hinge members 14 on the far side of the top and bottom boards of said gate. Said hinge members are also secured to the boards by bolts 16, and are braced by struts 17 which extend diagonally from the hinge members to the struts 12, being secured by bolts 18 to each one thereof. The hinge members 13 extend around the hinge members 5 and return upon the opposite side of the gate, as shown in Figure 3; the hinge members 14 surround the hinge members 5 and overlie the looped portions of the members '13 at all points, thus producing doubled looped portions which are bolted to the gate through the end strut 12 by means of bolts 15. These doubled looped portions produce a very strong connection, and the shearing stresses of the bolts 15 and 16 that secure the hinge members 13 and 14 to the gate are resisted by the struts 17, thereby producing a strong and rigid connection for the gate, and one which is not readily affected by the bending moments produced by the gate. This is a very desirable feature since the greatest strain is produced in that section of the gate 7 defined by upper hinge members 13 and 14.

It will accordingly be observed that I have invented a strong rigid hinge for a gate that has a double looped portion whereby the resistance thereof is double that of a single loop, and the weight carrying strength of the gate is doubled, and have connectedthe same to the gate to produce a rigid connection that prevents sagging and reduces the liability of parts working loose on account of strain caused by the forward weight of the gate.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and Itherefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim asmy invention:

1'. A hinge construction for a farm gate comprising hinge members adapted to be secured on opposite sides oi the gate, said members extending beyond the rear of the gate in overlapping relation and returning upon opposite sides thereof in overlapping relation to provide a double thickness at the point of greatest shear. I

2. A hinge structure for a farm gate oo1nprising hinge members defining a loop at the rear end of said gate a bearing block secured in said loop and having a depending leg, said depending leg having a rounded projection adapted to contact the anchoring bolts of the gate to preclude the gate from being raised when in closed position.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
